Before GMT, time was a local affair that created global chaos
In short: Imagine a world where every town kept its own time based on the sun's position. This video explores how humanity moved from localized clocks to a unified global standard.
The transition to Greenwich Mean Time (GMT) was a collaborative effort between astronomers, mathematicians, and global powers. Before this standardization, inconsistent timekeeping caused significant confusion and even posed dangers in navigation and trade.
The video highlights key milestones in the mastery of time, including George Biddell Airy's Prime Meridian, the Shepherd Motor Clock, and the Observatory Time Ball at Greenwich. These innovations were essential for solving the problem of longitude at sea and eventually establishing global time zones.
